Mutation operator for a GA; changes a single element in a string by
changing it to the next in the sequence deducted from the chromosome
Creates a new mutation operator.
Applies mutation operator to a "Chromosome", a string, really. Can be applied only to victims with the _str instance variable; but it checks before application that both operands are of the required type. The chosen character is changed to the next or previous in the array of chars used for coding the the string my $strChrom = new Algorithm::Evolutionary::Individual::String ['a','c','g','t'] 10; my $xmen = new Algorithm::Evolutionary::Op::IncMutation; $xmen->apply( $strChrom ) # will change 'acgt' into 'aagt' or # 'aggt', for instance
